2. Shortness of breath
If you experience shortness of breath while doing your day to day tasks, you need to get checked for lung cancer. This may occur due the lung tumor blocks, narrowing of airway or fluid building up in the chest.
3. Chest and bone pain
If you experience pain in the chest, shoulder or back area, there are chances that lung cancer has spread to the bones causing the pain. There could also be a number of neurological symptoms and headaches if the cancer has spread to the brain. So consult a doctor if the pain doesn’t go away.
